Hence the area, over which the cleavage of the slate and the foliation of the metamorphic schists extends with an average W.N.W.

-Stratificationof metamorphic schists.-Foliationof intrusive rocks.-Relation of cleavage and foliation to the lines of tension during metamorphosis.

The so-called beds in the metamorphic schists, so unlike common cleavage laminae, seems the best, or at least one argument against such a suspicion.

Near the bifurcation of the Beagle Channel, where the underlying metamorphic schists are first seen, they are foliated (with some irregularities), in this same W.N.W.
